I worked at U.S. Office of Personnel Management full-time for more than 4 years

Pros

I can't think of any

Cons

Disorganized, lack established procedures, cronyism , lack of diversity, favoritism, no ethics, horrible culture of favoritism, cronyism, no values. If you are educated and have values and work ethic, stay away.

Advice to Management

hire a diverse group of managers, people with some education. Keep your racial biases in check.
